SCOPE AND PURPOSE
The U.S. Environmental Protection Agency (EPA) began regulating fine particles
in July 1997. The regulation set forth the reference monitoring method in the
Code of Federal Regulations (CFR) at 40 CFR Part 50, Appendix L. This
document is intended to assist the Electronic Calibrations Branch (ECB) with the
North Carolina Division of Air Quality (NCDAQ) to use the EPA reference method
to monitor the ambient atmosphere for particles with an aerodynamic diameter of
2.5 µm or less, known as fine particles (PM2.5). Fine particles are formed in the
atmosphere from gases such as sulfur dioxide, reactive oxides of nitrogen, and
volatile organic compounds. Sources include power plants, diesel trucks, wood
stoves, and industrial processes.
The goal of the NCDAQ PM2.5 program is the measurement of fine particles in
units of micrograms per cubic meter (μg/m3). Using a Rupprecht & Patashnick
Partisol®-Plus Model 2025 PM 2.5 Sequential Sampler, particles are collected on
2.24 PM2.5
Section 1
Revision 2011

Page 6 of 30
47mm diameter, 2µm pore-size Teflon® filters over a 24-hour time period. The
concentrations are then compared to the National Ambient Air Quality Standard
(NAAQS) of 35 μg/m3 for 24 hours and 15 μg/m3 annual arithmetic mean
concentration.
This document focuses on the assembly and repairs of the Rupprecht &
Patashnick Partisol®-Plus Model 2025 PM 2.5 Sequential Samplers and should be
used in conjunction with the supplied Service Manual. The Service Manual is the
reference method for all adjustments to the sampler by ECB technicians and will
not be reproduced in this Standard Operating Procedure (SOP).

SAMPLER DESCRIPTION AND ASSEMBLY
2.1
Description of the R&P Model 2025 PM2.5 Sequential Sampler:
The Partisol® -Plus Model 2025 Sequential Air Sampler is designed to meet the
regulatory monitoring requirements for PM2.5 (40 CFR Part 50, Appendix L). The
sampler draws a known volume of air at a constant flow rate through a PM10 inlet
followed by a Well Impactor Ninety-Six (WINS). After a 24-hour sampling period,
the pre-weighed Teflon® filter is collected and gravimetrically analyzed. The mass
concentration is reported as μg/m3.
Features of the Partisol® -Plus Model 2025 Sequential Air Sampler:
•
An active volumetric flow control system that maintains a constant volumetric
flow rate of 16.67 L/min by incorporating a mass flow controller, and ambient
temperature and pressure sensors.
•
The temperature of the collection filter is maintained within 5 °C of the outdoor
ambient temperature by a continuous filter compartment ventilation system.
•
The inlet is designed to remove particles with an aerodynamic diameter of
greater than 10 µm and sends particles less than 10 µm to the next filtration
stage. Figure 1 is a schematic of the PM10 inlet head.

•
Figure 2 depicts the WINS impactor that removes particles greater than 2.5 µm
and allows 2.5 um in diameter and smaller particles to be collected on a Teflon®
filter.
•
The sampler uses standard 47 mm Teflon® filters housed in reusable cassettes.
•
The sampler has a filter exchange and storage system that simplifies
transportation, minimizes contamination and allows for up to 177 hours between
site visits.
•
A record of filter data is stored for each filter used in the sampler, and includes all
U.S. EPA specified values such as error condition flagging and average
temperatures and pressures. Filter data records also include sampled volume
and analog input data averaged over the collection period.
•
The sampler has a capacity to store 50 filter data records.
•
Interval data are stored every five minutes, and include the five-minute averages
of the filter temperature, ambient temperature, ambient pressure, and flow rate.
•
The sampler has capacity to store 16 days of five-minute interval data.
•
The sampler has capacity to store 32 days of 30 minute input data.
•
A bi-directional RS232 interface for data transfer to or from a PC or Palmtop
device.

APPENDIX B Deciphering Hexadecimal Status Codes
When the Partisol-Plus Sampler’s PRC 5: Status Codes are downloaded, they are displayed as
hexadecimal numbers. This appendix explains how they relate to the sampler’s status codes.
The hexadecimal number system is a base-16 number system that uses 16 symbols (0, 1, 2, 3,
4, 5, 6, 7, 8, 9, A, B, C, D, E and F) to represent number values.

When downloaded, the Partisol-Plus Sampler’s Status Codes are displayed in hexadecimal
form. The sampler may display more than one code at a time. When the unit does show more
than one status code, it adds the codes together and displays them as a hexadecimal sum.
For example, if the unit displays the Flash Memory status code (hexadecimal number “1”) and
the System Reset Occurred status code (hexadecimal number “4”) at the same time, the two
status codes (when downloaded) will be displayed as the hexadecimal number “5.” The Status
Code Table has only two status codes that would add up to a value of “5”. By looking at this
table and breaking down the downloaded status codes, you can determine which status codes
the unit has displayed. To properly use the Status Code table, you must separate the status

codes on the table into place holders: the “1’s,” “10’s,” “100’s,” “1,000’s,” “10,000’s,” and
“100,000’s” and the “1,000,000’s” place. To break down the downloaded status codes, you must
match each section of the status code with these place holders. Refer to the following two
examples for assistance with deciphering hexadecimal status codes.
Example 1: Decipher the following downloaded status code: 20C30
1. First, look at the Status Code table and break down the status code into its different
place holders:
2. There are no status codes displayed in the “1’s” place of the original status code.
3. In the “10’s” place of the original status code, a status code of “30” is displayed. Because
there are no status codes in the table that match this number, you will need to break
down this number further. In the “10’s” place of the table, there are only two status codes
that, when added together, will amount to “30”: “10” Flow 1 Out of Range and “20” Flow
2 Out of Range. These are two of the status codes that the unit is displaying in its
original status code. Now, subtract “30” from the original status code: 20C30 – 30 and
you are left with “20C00”.
4. In the “100’s” place of the new status code (20C00), a status code of “C00” is displayed.
Because there are no status codes in the table that match this number, you will need to
break down this number further. So, convert C00 to a decimal number. From the table,
you see that “C” is 12, which converts “C00” to “1200.”
5. In the “100’s” place of the table, there are only two status codes that, when added
together, will amount to “1200”: “400” Ambient Sensor Out of Range and “800” Filter or
Compartment Temp Sensor Out of Range. These are two more of the status codes that
the unit is displaying in its original status code. Now, subtract “C00” from “20C00”:
20C00 - C00 and you are left with “20,000”.

6. In the “10,000’s” place of the Status Code table, the status code “20000” Coeff of
Variation for Flow 1 Too High, matches the “20,000” status code. This is the last status
code that the unit is displaying in its original status code. Therefore, the downloaded
status code, “20C30,” breaks down into the following status codes, according to the
Status Code table:
10 - Flow 1 Out of Range
20 - Flow 2 Out of Range
400 - Ambient Sensor Out of Range
800 - Filter or Compartment Temp Sensor Out of Range
20000 - Coeff of Variation for Flow 1 Too High.
Example 2: Decipher the following downloaded status code: 70B002
1. First, look at the Status Code table and break down the status code into its different
place holders:
2. ) In the “one’s” place of the original status code, a status code of “2” is displayed. In the
“one’s” place of the Status Code table, the “2” status code matches the 2 “Automatic
System Calibration Failed” status code. This is one of the status codes that the unit is
displaying in its original status code. Now, subtract “2” from “70B002”: 70B002 - 2 =
70B000. Continue to break down this status code to decipher the rest of the status
codes displayed in this number.
3. In the “10’s” place of the new status code, there are no status codes displayed.
4. In the “100’s” place of the new status code, there are no status codes displayed.
5. In the “1,000’s” place of the new status code (70B000), a status code of “B000” is
displayed. Because there are no status codes in the Status Code table that match this
number, you will need to break down this number further.

APPENDIX B Deciphering Hexadecimal Status Codes (Cont.)
6. Convert “B000” to a decimal number. From the table you see that “B” is “11”, which
converts “B000” to “11,000.” Next, look at the Status Code table to decipher the “11,000”
status code. In the “1,000’s” place of the table, there are three status codes that, when
added together, will amount to “11,000”: “1000” Electronics Temperature Out of Range,
“2000” Diff of Filter Temp 1 and Ambient Temp > ±5° C and “8000” Filter Exchange
Mechanism Failure. There are three more of the status codes that the unit is displaying
in its original status code.Now, subtract “B000” from “70B000”:70B000 - B000 and you
are left with 700000. Continue to break down this status code to decipher the rest of the
status codes displayed in this number.
7. In the “10,000’s” place of the new status code, there are no status codes displayed.
8. In the “100,000’s” place of the new status code (700000), a status code of “700000” is
displayed. Because there are no status codes in the Status Codes table that match this
number, you will need to break down this number further.
9. In the “100,000’s” place of the PRC 5: Status Code, there are three status codes that,
when added together, will amount to “700,000”: 100000 “Elapsed Sample Period Out of
Range,” (H) 200000 “Leak Check Failed” and 400000 “Audit Performed in Middle of
Sample.” These are three more status codes that the unit is displaying in its original
status code. Therefore, the downloaded status code, “70B002,” breaks down into the
following status codes, according to the Status Code table:
2 - Automatic System Calibration Failed
1000 - Electronics Temperature Out of Range
2000 - Diff of Filter Temp 1 and Ambient Temp > ±5° C
8000 - Filter Exchange Mechanism Failure
100000 - Elapsed Sample Period Out of Range
200000 - Leak Check Failed
400000 - Audit Performed in Middle of Sample.
